Answer:
They can sit in 19,958,400 ways
Explanation:
The seating arrangements matter based off of rank, which means that we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
![P_((n,x)) = (n!)/((n-x)!)](https://img.qammunity.org/2021/formulas/mathematics/college/iftsizhotvl3emolg16e3ljeid6iz7usn1.png)
In this question:
8 seats from a set of 12. So
![P_((12,8)) = (12!)/((12-8)!) = 19,958,400](https://img.qammunity.org/2021/formulas/mathematics/college/kr4dn529zcongolacpengg310njw2nb7o1.png)
